NON-REFILLABLE BOTTLE.

Application filed July 10, 1919.

1 b all whom it may concern:

Be it known that I, HAROLD G. POLK, a citizen of the United States, residing at Orient, in the county of Faulk and State of South Dakota, have invented certain new and useful Improvements in Non-Refillable Bottles, of which the following is a specification.

This invention relates to non-refillable botties, and the object thereof is to provide a simple and cheap bottle which when emptied can not again be refilled either with or without detection.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter de scribed and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 represents a vertical central section of a bottle constructed in accordance with this invention, and

Fig. 2 is a detail vertical section showing the auxiliary bottom in locked elevated position.

In the embodiment illustrated, a bottle 1 is shown of glass, or other suitable material, having the usual integrally formed bottom 2 which is provided with a plurality of apertures 3 for the passage therethrough of wire hooks l. These hooks 4 are carried by a vertically movable false bottom 5 which is threaded fluid-tight in the bottle, being preferably covered with a protective packing 6 which extends down around the periphery of the bottom between the edge thereof and the side walls of the bottle. Depending from the false bottom 5 at diametrically opposite points are spring housings 7 in which are mounted spring projected locking pins 8 adapted to extend radially beyond the edge of the bottom 5 when projected. Coiled springs 9 are located in these housings at the rear of said pins 8 to project them as is shown clearly in Fig. 2.

The bottle 1 has near its upper end a groove 10 which is designed to receive the pins 8 when the bottom 5 reaches its extreme Specification of Letters Patent.

upward or outward position as is shown clearly in Fig. l in dotted lines.

A coiled spring 11 is arranged between the false bottom 5 and the bottom proper of the bottle and is designed to exert its tension to force the bottom upwardly, the tension of said spring being normally counterbalanced by the weight of the contents of the bottle.

The wire hooks 4 which extend through the apertures 3 in the bottom 2 of the bottle are designed to hold the bottom 5 in lowered position during the filling of the bottle, and after it has been filled, these hooks are turned and moved upwardly into the bottle so that access thereto can not be obtained. The hooks lhave shanks 4 which are engaged with eyes 12 carried by the lower face of the bottom 5 as is shown clearly in Fig. 1.

The bottle mouth is shown equipped with a spout 13 having a regulating faucet 14, although obviously it may be closed by any suitable stopper.

To remove the contents of the bottle, the stopper is removed or the faucet 14L opened and the liquid poured out and when it has been emptied, the bottom 5 will rise under the action of spring 11 into the dotted line position shown in Fig. 1, when the spring projected pins 8 will snap into the groove 10 of the bottle and lock the false bottom in this position so that access to the pins is impossible, consequently the bottle can not be again refilled.

From the foregoing description, taken in connection with the accompanying drawings, the advantages of the construction and of the method of operation will be readily apparent to those skilled in the art to which the invention appertains and-while I have described the principle of operation of the invention together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that the device shown is merely illustrative and that such changes may be made as are within the scope of the claimed invention.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is c A non-refillable bottle having apertures in the bottom thereof, a false bottom mounted liquid-tight to slide in said bottle,

hook-shaped wires carried by said false bottom and extending through the apertures in the bottom proper and adapted to engage said bottom to hold the false bottom in retracted position, a coiled spring arranged between said bottoms to project the false bottom when said Wires are released, spring projected pins carried by the lower face of said false bottom and adapted to extend be yond the periphery thereof, when projected,

and :1v groove near the top of the bottle to 10 receive said pins whereby the bottom is Jocked in elevated position.

In testimony whereof I aflix my signature in presence of two witnesses.
